Rihanna -- Slams CBS for Pulling Her from Ravens Game

7:53 AM PT -- CBS released a statement saying they will NOT use Rihanna's performance going forward, saying, "Beginning this Thursday, we will be moving in a different direction with some elements of our Thursday Night Football open. We will be using our newly created Thursday Night Football theme music to open our game broadcast."

It took a few days, but Rihanna is finally lashing out about CBS' decision to yank her musical opening from "Thursday Night Football" last week and air it this week instead ... and let's just say she's not happy.

With the Ray Rice scandal still fresh, and the Ravens set to play the Steelers, CBS opted not to run a taped musical segment featuring Rihanna ... seeing as she had been the victim of high-profile domestic violence.

But with the segment now set to air this week, Rihanna took to Twitter to blast CBS, writing, "CBS you pulled my song last week, now you wanna slide it back in this Thursday? NO, F*** you! Y'all are sad for penalizing me for this."

As for what she means by "penalizing" ... it's pretty clear she feels CBS will not allow her to move on from getting beaten by Chris Brown 5 years ago.

She followed that up by writing, "The audacity ..."

Rihanna was in Barbados Monday ... looking extremely good.
